[0016] Optionally, the base is provided with guide rails; each guide rail corresponds to a movable frame; the movable frame is slidably mounted on the corresponding guide rail.

[0017] Optionally, the drive assembly includes a telescopic drive element and an elastic element;

[0018] The telescopic drive element is used to pull the rotating seat from a first angular position to a second angular position so that the movable frame is brought together.

[0034] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0036] This application provides a fireworks bundle packaging paper pressing mechanism, which is applied to fireworks packaging equipment to automatically press the packaging paper at the bottom and top of the fireworks bundle, thereby improving efficiency and reducing labor costs.

[0037] The firework pyrotechnic wrapping paper pressing mechanism provided in this application includes a base, a rotary drive mechanism, at least three movable frames, and connecting arms. The rotary drive mechanism includes a rotating seat and a drive assembly; the drive assembly drives the rotating seat to reciprocate. The movable frames are distributed around the rotating seat and are all slidably mounted on the base. Each connecting arm corresponds to one of the movable frames; the first end of the connecting arm is movably connected to the rotating seat, and the second end is movably connected to the corresponding movable frame. As the drive assembly drives the rotating seat to reciprocate, the rotating seat, through the connecting arms, drives the movable frames to converge and press the wrapping paper around the firework pyrotechnic wrapping paper, or to disperse it away from the firework pyrotechnic wrapping paper.

[0038] During operation, the packaging paper and fireworks are placed above the rotating base and surrounded by the moving frame. Driven by the drive assembly, the rotating base reciprocates between a first angular position and a second angular position. When the rotating base rotates to the first angular position, the moving frame disperses and separates from the fireworks; when the rotating base rotates to the second angular position, the moving frame converges and presses the packaging paper around the fireworks. Therefore, as the drive assembly drives the rotating base to reciprocate between the first and second angular positions, the rotating base can continuously converge and disperse the moving frame via the connecting arm, thereby continuously pressing the supplied packaging paper and fireworks.

[0039] The following is a detailed explanation of the above-mentioned fireworks packaging paper pressing mechanism with reference to the accompanying drawings.

[0040] refer to Figures 1-5 The fireworks packaging paper pressing mechanism includes a base 10, a rotary drive mechanism 20, at least three movable frames 30, and connecting arms 40. The rotary drive mechanism 20 includes a rotating seat 21 and a drive assembly; the drive assembly drives the rotating seat 21 to reciprocate. The movable frames 30 are distributed around the rotating seat 21 and are all slidably mounted on the base 10. Each connecting arm 40 corresponds to one of the movable frames 30; the first end of the connecting arm 40 is movably connected to the rotating seat 21, and the second end is movably connected to the corresponding movable frame 30. As the drive assembly drives the rotating seat 21 to reciprocate, the rotating seat 21, through the connecting arms 40, drives the movable frames 30 to converge and press the packaging paper around the fireworks, or to disperse it away from the fireworks.

[0041] Figure 4 The diagram shows the fireworks packaging paper pressing mechanism in a dispersed state on the moving frame, in which automated equipment or workers can pick up and put down the fireworks. Figure 5A schematic diagram is shown of the fireworks packaging paper clamping mechanism in the converged state of the movable frame 30. In this state, the movable frame 30 converges and clamps the packaging paper around the fireworks. Therefore, as the drive assembly drives the rotating base 21 to reciprocate, the fireworks packaging paper clamping mechanism... Figure 4 The state shown and Figure 5 Transitions between the states shown.

[0042] The drive assembly drives the rotating base 21 to move, and the rotating base 21 drives the various moving frames 30 to move via the connecting arm 40. The drive assembly may contain one or more drive elements and may be configured as various types of drive devices, such as electric devices, pneumatic devices, etc., without limitation.

[0043] In one embodiment of this application, the connection between the first end of the connecting arm 40 and the rotating seat 21 is detachable, and the connection between the second end of the connecting arm 40 and the corresponding movable frame 30 is also detachable. In this design, both ends of the connecting arm can be detached; therefore, the distance between the movable frames can be adjusted by replacing connecting arms of different lengths (distance between the connection points at both ends), thereby adapting to various sizes of firework pyrotechnics. It should be understood that the lengths (distance between the connection points at both ends) of each movable frame can be the same or different.

[0044] In one embodiment of this application, the rotating base is assembled in a detachable manner. This design allows for the adjustment of the distance between the moving frames by replacing different rotating bases, thereby accommodating various sizes of fireworks.

[0045] In one embodiment of this application, the movable connection between the first end of the connecting arm 40 and the rotating seat 21 is hinged, and the movable connection between the second end of the connecting arm 40 and the corresponding movable frame 30 is hinged. In a specific embodiment, both ends of the connecting arm 40 are connected by hinges and are detachably connected.

[0046] In one embodiment of this application, a guide rail 11 is arranged on the base 10; the guide rail 11 corresponds one-to-one with the movable frame 30; the movable frame 30 is slidably mounted on the corresponding guide rail 11. In this design, the guide rail 11 is used to guide the movement of the movable frame 30, which can increase the stability of the movable frame 30 during the movement process.

[0047] In one embodiment of this application, reference is made to Figure 3 The drive assembly includes a telescopic drive element 221 and an elastic element 222. The telescopic drive element 221 is used to pull the rotating seat 21 from a first angular position to a second angular position to bring the movable frame 30 together. The elastic element 222 is used to pull the rotating seat 21 from the second angular position back to the first angular position to disperse the movable frame 30. In one specific embodiment, the telescopic drive element 221 is a cylinder, and the elastic element 222 is a spring.

[0048] During operation, the telescopic drive element 221 and the elastic element 222 work together to drive the rotating seat 21 to rotate between a first angular position and a second angular position. When the telescopic drive element 221 pulls the rotating seat 21 from the first angular position to the second angular position, the elastic element 222 is stretched, and the rotating seat 21 drives the moving frames 30 to converge via the connecting arm 40. The moving frames 30 then compress the wrapping paper around the firework pyrotechnica. When the elastic element 222 pulls the rotating seat 21 back from the second angular position to the first angular position, the rotating seat 21 drives the moving frames 30 to disperse via the connecting arm 40. The moving frames 30 separate from the firework pyrotechnica, at which point the compressed firework pyrotechnica can be removed and replaced with new wrapping paper and the firework pyrotechnica.

[0049] It should be understood that when the telescopic drive element 221 is a cylinder, during the process of the elastic element 222 pulling the rotating seat 21 from the second angle position to the first angle position, the telescopic drive element 221 is in a follow-up state and does not apply driving force to the rotating seat 21, so that the elastic element 222 can pull the rotating seat 21 to rotate.

[0050] In one embodiment of this application, the drive assembly further includes a limiting bolt 223. A limiting support 12 is provided on the base 10, and the limiting bolt 223 is mounted on the limiting support 12. When the elastic element 222 pulls the rotating seat 21 from the second angular position back to the first angular position, the end of the limiting bolt 223 abuts against the rotating seat 21. In this design, the limiting bolt 223 is used to restrict the rotating seat 21 from continuing to rotate. Under the combined action of the limiting bolt 223 and the elastic element 222, the rotating seat 21 can rotate to the first angular position and remain at the first angular position.

[0051] Furthermore, it should be understood that the operator can also adjust the first angle position by turning the limit bolt 223. Figure 3 In the structure shown, when the limiting bolt 223 is turned, the limiting bolt 223 can extend or retract relative to the limiting support 12, and the end position of the limiting bolt 223 changes, thereby changing the blocking position of the limiting bolt 223 (corresponding to the first angular position of the rotating seat 21).

[0052] In one embodiment of this application, the base 10 has a plate-like structure; the rotating seat 21 passes through the through hole of the base 10. The movable frame 30 is arranged on one side of the front of the base 10, and the rotary drive mechanism 20 is arranged on one side of the back of the base 10. This design makes full use of the space on both sides of the base 10, and the structure is compact and reliable.

[0053] In one embodiment of this application, the movable frame 30 includes a first movable frame, a second movable frame, a third movable frame, and a fourth movable frame. The first movable frame, second movable frame, third movable frame, and fourth movable frame are evenly distributed around the rotating base 21. (See reference...) Figure 4 and Figure 5 Each of the four movable frames 30 corresponds to a connecting arm 40. When the rotating base 21 rotates, the four connecting arms 40 pull their respective movable frames 30 to move. In this structure, the movable frames are 90° apart, making it suitable for square fireworks.

[0054] Furthermore, it should be understood that the number and angle distribution of the movable frames can also be adapted to change as the shape of the firework pyrotechnic changes. In this application, the number of movable frames can be 3, 4, 5, 6, 7, 8, 9, 10, ...

[0055] This application also provides a fireworks packaging device, which includes any of the aforementioned fireworks bundle packaging paper pressing mechanisms. The fireworks packaging device is used to cover the fireworks bundle with packaging paper. The fireworks bundle packaging paper pressing mechanism can be used to automatically press the packaging paper at the bottom and top of the fireworks bundle, thereby improving efficiency and reducing labor costs.

[0056] In this embodiment, the fireworks packaging paper pressing mechanism includes a base, a rotary drive mechanism, at least three movable frames, and connecting arms. The rotary drive mechanism includes a rotating seat and a drive assembly; the drive assembly drives the rotating seat to reciprocate. The movable frames are distributed around the rotating seat and are all slidably mounted on the base. Each connecting arm corresponds to one of the movable frames; the first end of the connecting arm is movably connected to the rotating seat, and the second end is movably connected to the corresponding movable frame. As the drive assembly drives the rotating seat to reciprocate, the rotating seat, through the connecting arms, drives the movable frames to converge and press the packaging paper around the fireworks, or to disperse it away from the fireworks. For a more detailed explanation, please refer to the previous section on the fireworks packaging paper pressing mechanism; it will not be repeated here.
